• In the traditional digital channelized receiver, there is no simple algorithm to reconstruct the wideband cross-channel signal without distortion. Moreover, the analog-to-digital converter (ADC) limits the instantaneous bandwidth and dynamic range of the receiver. These problems restrict the applications of digital channelized receiver in radar and communication. Based on the principle of signal matched-phase, a novel channelized receiver structure is presented, where the sub-channels can be seamlessly combined. The presented structure uses the principle of signal matched-phase to solve the frequency ambiguity in the case of the multi-channel undersampling signals. It can reconstruct the wideband cross-channel signal with extremely low distortion, and that it avoids the use of high-speed and high-resolution ADC in wideband and high dynamic applications. Simulation results show the effectiveness of the structure.
